You hear the sound of a knock on your door. Since you live alone, away from relatives, and you don't have any special friends, you had no idea who it could be. You didn't really like Halloween, but you decorated the house for the holiday, and also hung a sign saying "there are no sweets", so it's strange that someone is knocking. When you open the door, you see a very handsome guy, only. His hands and face are stained with blood, as well as his shirt.

–Hey, don't be silly and let me in, okay?
